System volume sliders need to be distinguished

I think the two volume sliders belonging to Discord on the Windows sound mixer should get different names, so we would know which one to adjust by a glance. I have to mute myself to see that little green bar raising up slightly to recognize which slider to lower before I make a call. We all know that people talk very quietly compared to notification sounds and since the two sliders reset to default after every operation system restart, this is an ongoing issue.
